To all whom it'may concern: 7

-Be it known that I, SAMUEL G. GREEN, lieut., Ordnance Department,United States Army, a citizen of the United States, stationed atWashington, D. C., have invented an Improvementin Shoulder-Rests forGuns, of which the following is a specification.

The invention described herein may be used by the Government, or any ofits officers or employees in prosecution of work for the Government, orby any other person in the United States, without payment of any royaltythereon.

The object of my invention is to provlde a novel shoulder-rest formachine guns, etc., in which the shoulder-rest-piece may be quickly andeasily adjusted relative to its support, to meet the requirements ofdifferent operators.

With this object in view, the invention resides, generally stated, in ashoulder-rest embodying a support attachable to agun, and having adepending standard or post, on which is mounted a slidableshoulder-restpiece, the standard and the shoulder-restpiece having atongue-and-groove connection, and means for frictionally holding theshoulder-rest-piece in adjusted position.

For a fuller understanding of the invention, reference may be had-to theaccompanying drawings in, which like reference characters designatecorrespondin parts throughout the several views, which latter may bebriefly described as follows Figure 1 is a plan view of my shoulderrest;

Fig. 2 is a view in side elevation thereof;

Fig. 3 is a bottom plan view, partly insection, thereof; and

Fig. 4 is a detail view, in side elevation, of the member which isattachable to the gun, and which carries the support for theshoulder-rest-piece.

Referring, now, in detail to the drawingsi 1 designates a tubular memberhaving a longitudinal slit 2, extending from one end thereof andterminating short of the other end. This tubular member is slipped overan extension of the stock of the machinegun, and isfrictionally clampedthereto by means of a clamping-bolt 3, hinged at 4 toa strap 5, passingpartly around the member 1, at the split portion thereof, and havingears 6, 6, between which said clamping bolt 3 is adapted to project, thethreaded portion 7 of the bolt carrying a wing nut 8, wh1ch may bescrewed against the ears 6, 6, thereby tending to contract the tube 1and bindit upon the extension of the stock. Said tubular member and themeans for securing the same to the stock of the gun form no part of thisinvention.

Carried by the tubular member 1, at'the end thereof opposite the strap5, is a depending standard or'post 9, provided with a longitudinal slot10, and with longitudinal grooves 11, 11 in the sides thereof.

Slidable on said standard-9 is a shoulderrest-piece comprising a slide12, having a lateral wing 13 preferably transversely corrugatedthroughout a portion of its length, as shown at 14. The slide ispreferably constructed of sheet metal stamped to shape, and is providedwith longitudinal flanges or lips 15, 15 entering the grooves 11,11.Thus, the standard 9 and the slide 12 have a tongueand-grooveconnection.

Suitable means are provided for frictionally holding the slide inadjusted position, and in this instance, such means preferably comprisea clamping bolt 16, passing transversely through the sides of the slide12 and having a cross-sectionally squared portion 17 to fit the slot 10and prevent rotation of the bolt therein, and havin also, a threadedportion 18, on which is t readed a wing nut 19. In operation, byscrewing up the nut 19 on the bolt 17 the sides of the slide 12 will becaused to frictionally bind against the sides of the post 9, and therebyfrictionally hold the slide in adjusted position.

It will be noted that, by the construction described, I have provided ashoulder-rest of exceedingly simple construction in wich theshoulder-rest-piece is easily and quickly elevated or lowered on thesupport (such as the post or standard 9), to suit the requirements ofdifferent operators.

Having thus fully described my invention, what I claim as new and deslreto secure by Letters Patent, is

1. A shoulder rest including a member attachable .to the rearwardlyprojecting cylindrical portion of a machine gun stock, a dependingstandard integral with said member at the rear end thereof, saidstandard provided with a longitudinal slot, a shoulder rest pieceslidable on said standard and means passing through the slot andengaging rear end thereof, said standard provided with a longitudinalslot, a shoulder rest 10 piece slidable on said standard and meanspassing through said slot and engaging the shoulder rest piece forclamping the piece in selected position upon said standard.
